Geothermal Country Notes
There are no high-temperature geothermal resources in Ireland and all instances of low-temperature potential are only suitable for direct utilisation. To date, only one of the 42 warm springs located in the east and south of the country has been exploited, for heating a swimming pool.
The country does however possess an adequate supply of groundwater sources suitable for heat pumps. Since the late 1990s, the market has grown significantly so that now more than 1 500 domestically installed systems (typically, 12-14 kW) exist. This trend is expected to continue. Additionally, more than 30 large-scale heat pumps have been installed in commercial buildings. In total, heat pumps represent some 20 MWt of installed capacity.
